 | | The orbital speed of a body, generally a planet, a natural satellite, an artificial satellite, or a multiple star, is the speed at which it orbits around the barycenter of a system, usually around a more massive body. |
 | | It can be used to refer to either the mean orbital speed, the average speed as it completes an orbit, or instantaneous orbital speed, the speed at a particular point in its orbit. |
 | | This is still a simplified version; it doesn't allow for elliptical orbits, but it does at least allow for bodies of similar masses. |
